EVALUATION OF CORN HYBRIDS IN ALABAMA, 1995

INTRODUCTION
Selected varieties of corn hybrids are evaluated annually by
the Alabama Agricultural Experiment Station as a service to
producers and industry. These tests are spread throughout the
state in an attempt to determine effects of different climatic
factors and soil types on yield. There are several types of
tests in the program. The Preliminary Hybrid Tests are conducted
at one location in each of the northern, central and southern
regions of the State. These tests include experimental and newly
released hybrids. If a hybrid is outstanding in the preliminary
test it is entered in the Regular Corn Hybrid Test in the
following year.
The Regular Corn Hybrid Test is conducted at three locations
in the northern region, three locations 
in the central region and
four locations in the southern region. Early yellow corn hybrids
are tested at one location in each region. A white corn hybrid
test is conducted at Crossville in northern Alabama. In
addition, one regular corn hybrid test is irrigated at Headland
in southern Alabama. Locations and cultural practices for all
tests are shown in Table 1.

PROCEDURE
All tests are laid out in a randomized complete block design
with four replicate plots for each variety at each location.
Rows were 30 to 36 inches apart, depending on location. Two-row
plots are used, and both rows are harvested. Plots are 20 to 30
feet long, depending on location. The target plant population
for the tests is 20,000 plants per acre with a seeding rate of
23,000 seeds per acre. Th e irrigated tests at Headland are
seeded at a rate to achieve 30,000 plants per acre, but are
thinned to 25,000 plants per acre.
Grain yields are adjusted to 15.5 percent moisture and
converted to bushels (56 lb) per acre. Stalks broken or leaning
more than 45 degrees are considered lodged. The mid-silk data
show the number of days from planting until approximately half
the plants in the plots are showing silks. The Regular Corn
Hybrid tests also are examined for disease incidence at selected
locations each year. When virus or other disease symptoms
indicate crop damage, disease ratings are compiled and published
in this report. However, in 1994, no disease ratings were taken.
INTERPRETATION OF DATA
In replicated experiments such a's those reported here,
variation. Given this situation it is clearly necessary to have
a method to determine whether differences among hybrids are
"true" or "real" differences, or whether they are due to random
variation. To do this a statistical analysis is conducted to
determine a "least significant difference" (LSD) by comparing the
differences among varieties with random variation. If the
difference in yield between two hybrids is larger than the LSD,
then the difference is probably real, but if the difference is
less than the LSD, it may not be real. If the difference between
two hybrids is less than, but close to the LSD, then there is
still a chance that it is real, but if it is considerably smaller
than the LSD, then it is probably not real and mainly due to
random variation.
With this in mind it is very important to study differences
in hybrid yields in relation to the LSD which is provided at the
bottom of the table for each of the current year yield columns at
each location. Clearly, LSD's vary from one location to another.
This is because random variation varies among locations and from
year to year. The coefficient of variation (CV) is a reflection
of random variation, and is reported below the LSD values in the
tables. If the CV is low a precise or reliable test is
indicated. Ideally, the CV should be below 10 percent, but CV's
of 10 to 20 percent are acceptable. Values for the CV above 20
percent indicate a rather unreliable test, which may have been
-3-
caused by factors such as disease 
variation among replicates,
etc.
In comparing yield potential 
of two hybrids it is, important
to co nsider a wide range of results. 
Do not focus on results
from only one year at one location. 
Two- and three-year average
yields. are provided by location and 
region. These are more
useful guides than yields from only 
one year. However, other
factors may deserve consideration. For example, 
the differences
between the highest and the lowest 
yield of a hybrid across
several locations may. be an indication 
of the stability of its
yield, under variable conditions, or what 
the "risk, level" of the
variety is.
Differences in yield of hybrids among locations 
will be a
result of the combined effects of differences 
among locations in
soil, weather (mainly rainfall), planting 
date, weed control, and
other factors. To assist in estimating 
which factors most likely
had the greatest effect on yield differences 
among locations,
planting dates and cultural practices (Table 
1) , rainf all records
(Table 17) and soil types (Table 18) are provided. 
This
information also serves as a guide for assessing 
conditions to
which results may be extrapolated.

VIRUS DISEASE REACTIONS OF SOME HYBRIDS IN 1995
The most prevalent virus diseases of corn 
in Alabama are
maize chlorotic dwarf (MCD), caused by the 
maize chlorotic dwarf
virus (MCDV), and maize dwarf mosaic (MDM), 
caused .y the maize
dwarf mosaic virus (MDMV). Discovery 
of MDM in the State dates
back to the early 1960's, while MCD has 
been recognized since
1973. Both diseases probably occur throughout 
Alabama; however,
they generally have been more prevalent and damaging 
in the
northern two-thirds of the State. In 1995, 
these virus diseases
were not detected at any location.
Northern leaf blight, normally a cool 
season disease, has
occurred sporadically in South Alabama for 
the past two seasons
(1994 and 1995). It has caused serious disease 
losses in certain
corn fields, exceeding 50% loss in yields in 
a few isolated
cases. Disease resistant hybrids are the most 
economical means
of dealing with this troublesome disease. 
Corn hybrids at the
Brewton Experiment Field were rated for 
their reaction to
northern leaf blight in 1995. The results are 
given in Table 19.
Why this disease has been a problem recently 
in Southern
Alabama remains a mystery. It is normally favored 
by moderately
temperate (i.e. 64 to 87 degrees Fahrenheit) 
conditions.
Perhaps, the causal fungus has adapted to warmer conditions.
Whether this disease will become a chronic problem or its
occurrence over the past two seasons is a fluke remains 
to be
seen.
